This full-day gladiator menu is a stark reconstruction of what Roman fighters actually ate. Built almost entirely on barley, legumes, and nuts, it reflects a diet engineered for cost efficiency, endurance, and survivability rather than enjoyment. Breakfast is a punishing bowl of plain barley porridge with a few figs and nuts. Lunch offers dense grain cakes with just enough honey to keep energy up. Dinner returns once again to barley in the form of a thick vegetable and legume stew finished with fish sauce. It is repetitive, heavy, and relentlessly functional, exactly as ancient sources describe.
